Ralph Harold Boston (born May 9, 1939) is an Americanathlete. He was an all around athletic star, but he is best remembered for his successes in the long jump during the 1960s. He was the first person to jump 27 feet (8.2 m).

Between the Olympic Games, Boston won the Amateur Athletic Union (AAU) national championship in the long jump in 1961, 1962, 1963, and 1964. He also had the longest triple jump for an American in 1963.

He returned to the Tokyo Olympics as the world record holder after losing the record to Igor Ter-Ovanesyan, then regaining the record a couple of months before the games. In the Olympic final, Boston exchanged the lead with Ter-Ovanesyan. Going into the fifth round, Boston was leading but fouled while both Lynn Davies and Ter-Ovanesyan jumped past him. On his final jump, he was able to jump past Ter-Ovanesyan, but couldn't catch Davies, winning the silver medal.

Although Boston lost the world record again to Ter-Ovanesyan, the national title and the #1 ranking in 1968, he continued to compete. When rival Bob Beamon was suspended from the University of Texas at El Paso, for refusing to compete against Brigham Young University, alleging it had racist policies Boston began to coach him unofficially.[2] In the Mexico City Olympics, Boston watched his pupil destroy the world record by jumping 8.90 (29' 2 1/2"). Hearing the announcement in metric distances, Beamon did not know the significance of his feat. It wasn't until Boston explained he had broken the world record by almost two feet that Beamon collapsed to his knees.

At 29 the veteran won a bronze medal, finishing third behind Beamon and Klaus Beer, completing his set of medals. Shortly after these Games, Boston retired.

Boston moved to Knoxville, Tennessee, after retiring, and worked for the University of Tennessee as Coordinator of Minority Affairs and Assistant Dean of Students from 1968 to 1975.[3] He was the field event reporter for the CBS Sports Spectacular coverage of domestic track and field events.[4] He was inducted into the USA Track and Field Hall of Fame in 1974, and the U.S. Olympic Hall of Fame in 1985.[5]

A Los Angeles Timesarticle on Boston (August 2, 2010), coinciding roughly with the 50th anniversary of his initial world record, described him as a divorced great-grandfather who is writing an autobiography. He divides his time between Atlanta, Georgia and Knoxville.
